Hi everyone,

I have a strange behaviour with fopiROOT/FairROOT: I have a minimal helloworld example (MickeyMouse.cc), that I can compile and use... as long as I do not link its executable to fopiROOTs .../build/lib/libField.so.0 -- if so, the execution will crash with a segmentation violation. To the best of my knowledge, this does not happen if I link it to another library in FairROOT, but I haven't tried every possible combination^^.

Is this a known behaviour? Has anyone tried to link to the .so's with success? Am I doing s.th. wrong?

Attached, there are my CMakeLists.txt, where l. 63 triggers the crash, and the Valgrind log, with ll. 96 ff. pointing to an error in PndFieldContFact.cxx. I am using revision 28577 of https://subversion.gsi.de/fairroot/fopiroot/trunk on a CentOS 7 machine with CMake 2.8.11.

Any help is welcomed! Cheers,
Philipp

Which version of FairSoft or FairRoot are you using? libField is normally loaded by pandaroot, but we moved to the new git packages and the instalaltion scheme has changed, while it seems you are using some obsolete version.

You mean for for FairSoft and for FairRot? Do you have a "base" folder inside your repository?

Hi,

sorry, not quite sure what you asked for -- is there an official version number? How would I determine it?
Meanwhile, here's the result of some "svn info":

Pandaroot repository has moved to FairSoft and FairRoot from git repository, while it seems you are still using the old svn base repository. This could produce your problem,
